Observing Summary:

We have already mention the problem with prospero command  mgo  and  go . 
Tonight, we did not have any problem with this. However, when reducing data
 from the previous six nights, several frames do not have keywords such as: 
DATE-OBS, TELESCOPE, OBSERVAT, OBJECT, RA, DEC, SECZ, MISFLTID.

This is making reduction quite difficult, and we had to add keywords to hundreds
of files. What's even more annoying it that different set of keywords are missing
in different frames. I do consider this problem to be quite serious. So far, there
has not been a missing JD value as well as DATE, but if that happens, those frame
 would be useless to us.  

We wonder if this problem is related to the  go  and  mgo  issues where lastfile 
and nextfile could not be updated for some frames.
